Dunn index

The Dunn Index is like a score for how good a group of things are organized. It is used to measure how well different groups are separated from each other. Think of it like a game of tug-of-war - each group is like a team and how much the other teams pull determines how far apart the teams are. The same thing happens with the Dunn Index - it measures how far apart the different groups are from each other. The higher the score, the better the groups are organized.
